The AH1902 is a high-sensitivity, micropower Omnipolar Hall-effect switch IC designed for portable and battery-powered consumer electronics, office equipment, home appliances, and industrial applications. It features internal pull-up and pull-down capability, a low average supply current of 4.3A at 1.8V, and operates across a supply range of 1.6V to 3.6V. Its hibernating clocking system minimizes power consumption, making it ideal for space-constrained designs. The output is activated by either a north or south magnetic pole, turning on when the magnetic flux density exceeds the operate point (Bop) and holding until it drops below the release point (Brp).
